10.How to attach hands
Place the movement directly on a flat metal plate or something similar to attach the hands.
Static weighting
We recommend the use of movement holder to attach hands.
For hands attachment, please use a special equipment.
When the movement receives a strong shock, it may be damaged.
<<Note: Power reserve hand setting>>
(1)The mainspring should be fully wound up before setting power reserve hand.
(2)Set power reserve hand at the fully wound up position of the dial graduation.
